A new study shows that the rise of atmospheric carbon dioxide that contributed to the end of the last ice age more than 10,000 years ago did not occur gradually, but was characterized by three "pulses" in ...

(Phys.org) —A team of researchers in Japan has found that Eurasia is twice as likely to experience severe winters over the next several decades because of melting Arctic sea ice. In their paper published ...

Thin and wispy cirrus clouds skirt the scrutiny of current climate models. To uncover that missing information, Pacific Northwest National Laboratory is leading an international effort to run coordinated ...

In May 2014, two new studies concluded that a section of the land-based West Antarctic ice sheet had reached a point of inevitable collapse. Meanwhile, fresh observations from September 2014 showed sea ice ...

Wrapped in pollution, dust diverts from its usual course and steers clear of water. The result, found researchers at Pacific Northwest National Laboratory, closes one more gap in understanding how—and when—cloud ...

NASA is carrying out its sixth consecutive year of Operation IceBridge research flights over Antarctica to study changes in the continent's ice sheet, glaciers and sea ice. This year's airborne campaign, ...

The climate is getting warmer, the ice sheets are melting and sea levels are rising – but how much? The report of the UN's Intergovernmental Panel on Climate Change (IPCC) in 2013 was based on the best ...

Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21,000 year ago, oceanographer Alan Condron of the University of Massachusetts Amherst ...
